For the APS-U removal and installation, current planning calls for a 12-month shutdown and testing period, prior to resumption of operations. It calls for quick installation of the magnet support system with assembly and installation alignment tolerance. A three-point, semi-kinematic vertical mount for the magnet modules is the approach to reduce time for alignment. The longest section is the curved FODO section (four quads with three Q-bends interleaved, and a three-pole wiggler). All magnets of the FODO section sit on a single piece of support structure in order to have a good control over the magnet-to-magnet alignment tolerance. It brings challenge to minimize the top surface deflection and maximize the first mode frequency of the magnet support structure that is supported at three points. These constraints call for the need of optimizing the magnet support structures. Details of the optimization, including three-point positioning, material selection, and topology optimization, are reported in this study.
